Episode notes
Suspect Open Joint Near Lacerations
- Always suspect an open joint if a laceration is near a joint, regardless of size.
- Explore the wound locally with anesthesia, irrigation, and probing to assess depth and joint involvement.
Use CT Scan for Diagnosis
- Start evaluation with X-rays to look for intra-articular air but expect low sensitivity.
- Use CT scanning for better detection as it shows near 100% sensitivity for joint violation.
Saline Load Test Limitations
- The saline load test can identify open joints by injecting saline and watching for leakage.
- It’s uncomfortable, variable in sensitivity, and mostly replaced by CT in many settings.
